Abstract
Disclosed herein is a conductive coating composition that includes a functionalized carbon nanomaterial and/or boron nanomaterial and a fluid component. The nanomaterial and fluid component forms hydrogen bond network in the disclosed composition. Because of the formed hydrogen bonds, the disclosed coating exhibits enhanced thermal or electrical conductivity. Also disclosed is a method to improve thermal or electrical conductivity of an existing coating composition.
Claims14
A method of enhancing the conductivity of a surface comprising:
- (a) applying a conductive coating to the surface;
- wherein the conductive coating comprises
- from about 85 wt-% to about 96 wt-% a fluid component comprising a polymer;
- wherein the polymer is a self-curing polymer, a thermoset polymer, or a thermoplastic polymer;
- wherein the polymer comprises polyacrylic acid, polyurethane, epoxy, or a mixture thereof, wherein the fluid component comprises a polymer and wherein the fluid component comprises one or more of a second functional group capable of forming a hydrogen bond;
- and
- from about 0.5 wt-% to about 10 wt-% a carbon nanomaterial;
- wherein the nanomaterial is a carbon nanomaterial having one or more of a first functional group capable of forming a hydrogen bond or a boron nanomaterial;
- and
- wherein the nanomaterial is dispersed within the fluid component;
- (b) curing the conductive coating to form a cured conductive coating;
- wherein the cured conductive coating is flexible and does not crack;
- and wherein the conductive coating's resistance is lower than the fluid component by at least about 10% when measured under the same conditions;
- and
- wherein the surface is a part of an aircraft.
